Device and method for detecting and measuring fiber properties

摘要

A device and method for measuring changes in denier, percent finish-on-yarn, interlacing of polymer fiber, and other fiber properties, in real time as the fiber is being manufactured. The device uses an electrode driven at a discrete voltage to induce a current which changes in amplitude and/or phase in response to changes in denier, finish-on-yarn and/or interlacing of a fiber. A sensing system samples the current and detects changes in the amplitude and/or phase. A computer, running an application program, quantifies the change and determines the applicable property.
